Was also looking for this. Went through all the trouble to setup the SMTP settings but they don't seem to do anything since there is no forgot password button.

Same here. I hadn't logged in for a while and I had my username/password stored in BitWarden so I'm pretty sure I am typing it correctly but it's not working. No way to reset password so I will lose all my data if I re-enable registration and create another user.

Edit: I stopped the HomeBox Docker Container and restarted it and I was then able to login with no issues using the BitWarden username/password. Something must have been in a weird state in HomeBox causing me to get invalid username/password errors.

Same. Restarting the container solved it.

This is EXTREMELY unsupported, but...

You can select the password hash of a working user, and replace the password field in the user table of the row containing the user in question with that password hash, then log in as them, and reset their password to whatever you want.

Make sure you have working backups before you do this.
